To ALL WHoM-IT MAYOONOERN:

. Be it known that-we, CARL C. T. THOMAS and FREDRIOK A. S, RAYMOND',v of Beverly, in the county of' Essex, and in the' State of Massachusetts, have invented ertain new and useful Improvements in Extension- Ladde'rsyand do hereby declare that the following isa full, clear, and exact description thereof', reference being 11nd to the accompanyingdrawings, and to theletters of reference marked thereon.

In the annexed drawings, forming part of th ie specifi cation Figure 1 is a. planview, andv v 'Figure 2 is a side view.

The nature of our invention consists in providing one side of a ladder with an adjustable foot, made ofirovn, brass, or other suitable material, in sneh a. manner that the leg of thev ladder can be made longer, if' desired,

To enable Others skilled in the argomake and use ourinvention, we'will proceed to describe its construction andgoperation. n v

' In the drawings, A represents a ladder, to One/side Of which the movable fotB'is attached. This foOt'B is made of iron, vbrassor other suitable material, and has two slots, a a, through it. It is attached to the side of the ladder A by means of the 'two screws b which run from the inner sideof the ladder through the vslots a a onthe foot B, and it isifastened at anypointdesired, by the thumb-screws c c. By this arrangement the movable foot'B can be extended below the foot of theladder, so as to adapt the'la'dder to any uneven or sloping ground, and thereby preventing accidents, which are always-more 'or less liable to occur when a. common ladder is raised on such ground. I

Having thus fully described our invention, what we claim as new, and desire to secure by Letters Patent, is- The movable fo'ot B, constructed and attached to the side of the ladder, substantially as and for the purposes herein set forth. v Intestimony that we claim the foregoing, we have hereunto set our hands, this fourth day of May, 1868.-
